how high does a ball need to be for a infield fly?

OBR 6.05 A batter is out when --
(l) An infielder intentionally drops a fair fly ball or line drive, with first, first and second, first and third, or first, second and third base occupied before two are out. The ball is dead and runner or runners shall return to their original base or bases;
APPROVED RULING: In this situation, the batter is not out if the infielder permits the ball to drop untouched to the ground, except when the Infield Fly rule applies.

SA, if the OP meant that the fielder allowed the ball to drop untouched, this is different from an intentionally dropped ball.

Read the approved ruling, the IFF was not called, batter NOT out.

If the fielder caught the ball, then let it drop, now you have an "intentionally dropped ball".

Just a smart play by the fielder.

To Op, did anyone protest the umpires explanation that the ball has to be higher than the backstop?
